a20->b18 head swap???

[�¬”’ Gen3_rAcR]

I don't know if it's possible buut.. I have a Gen3 accord with an A20A1 engine and my brother is doing a frankenstein VTEC swap.. so I was wondering if it would be possible to use his old head on my car.. he has a B18A1..

PS: I know it probs won't work.. but if it could, that wold kick A$$

cant mix and match engine families like that.

A's with A's, and B's with B's

no cross breeding allowed.

well.. is there any way I can make my engine DOHC? kuz The accord engines are gutless ... unless I get a weber quad carb hehe

do a swap if you want a dohc

[crxlvr]

an h22 from a prelude will swap in quite nicely.

[shepworldwide]

if you want to mix n match you could do an h23 and mate it to an h22

[94tegRS]

yeah you could, cuz they are both H series.

you can do it with the D series too. and I am not sure, but im guessing with the F and K and whatever other kind of engines honda has come out with.

[crxlvr]

yes you can mix and match motor families, buts they arent all bolt and run affairs, some you need special oil lines ran, wiring conversion, port matching, etc.

[94tegRS]

yeah, i knew about the oil lines, I am planning on building a CRVTEC. and knew about wiring stuff. but about port matching. isnt that something you do between the head and intake manifold or???

when yoiu put a B16 head onto the B20b block, making the head match the bore, is that called deshrouding or is that also port matching? thought I saw someonhe refer to it as deshrouding before but maybe they were talking about something different.

Thanks in advance,

Matt

yea i was wondering that too, also how do the head gasket fit onto different blocks that have different bores? i just dont get that...

[crxlvr]

all the b-series blocks have the same bore, thats why this is possible. anyhow, port matching is in reference to mating a new exhuast header or manifold to the swapped block.


lyrical poisin - yes you can.

[nickzed20]

so, if you were to bore out your cylinders... then what would you do for a head gasket?

[crxlvr]

you would prolly have have the machine shop take car eof that for you, or find a company that makes special head gaskets for the amount of boring you have done.

[nickzed20]

oh ok... that makes things much clearer

but one more thing is that i noticed the b20 actually has a different bore then the other b series, so would the head (being made for a smaller bore) not create any interfearance?
